Did a good job for me
I was not able to purchase a replacement lower control arm assembly for my 1968 Chevy truck. None available anywhere from anybody. So I contacted a ball joint manufacturer and got the specs for the heavier ball joint in the 3/4 ton version of lower control arm. Got the correct 10 degree taper reamer from you and reamed the lower hole in my spindles and all is good. Saved a ton of money, thanks.
